Description

[Detailed Description of the Invention] <Industrial Application Fields> The present invention relates to a hook button for a telephone holder in a facsimile machine, telephone equipment, etc. This invention relates to an improvement in a hook button mechanism that turns on and off a communication line in conjunction with the raising and lowering of a device.

<Prior art> Conventionally, the above-mentioned hook button has been formed to protrude elastically from the receiving surface of the holder, and when the handset is placed on the holder, the hook button is pressed and swings about the fulcrum shaft, which connects the communication line. The entrance is being carried out.

<Problems to be Solved by the Invention> Incidentally, in the above-mentioned hook button, the bearing member that supports the fulcrum shaft is fixed to the holder via attachment means such as screws or caulking, which requires a lot of effort to process and assemble. At the same time, there were problems such as an increase in the number of parts and an increase in cost.

Therefore, in the present invention, the bearing member is formed integrally with the holder, and the fulcrum shaft of the hook button can be attached to the bearing member with one touch without using screws or caulking. The main purpose is to solve problems.

<Means for solving the problem> In order to achieve the above object, in the hook button according to the present invention, a part of the circumferential surface of the hook button provided in the holder of the telephone device is cut out. In addition to forming a flat part, a part of the peripheral surface of the bearing hole that receives the fulcrum shaft is cut out to form an opening, and the width of the opening is formed to be smaller than the diameter of the bearing hole. The flat part of the fulcrum shaft is inserted through the bearing hole, and the flat part is mounted in the bearing hole.

<Function> Since the present invention is constructed as described above, the flat part of the fulcrum shaft can be simply inserted into the bearing hole through the opening, without using conventional fixing devices such as screws or caulking. The hook button can be easily attached to the holder, which reduces the number of parts and simplifies processing time, and since the structure is extremely simple, the total cost can be reduced.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

1 to 4 show an example in which the present invention is implemented in a telephone holder for a facsimile.
In this drawing, reference numeral 1 is a facsimile, and an upper case 3 is formed so that it can be opened and closed with respect to a main case 2 using a horizontal axis as a fulcrum. The upper case 2 is provided with a telephone operating section 5, a manuscript paper insertion slot 6, a window 22 for checking the remaining amount of sensitive roll paper, and the like.

Furthermore, a document paper outlet 4 is provided between the rear edge of the upper case 3 and the main body case, and a sensitive roll paper outlet 7 is provided between the front edge of the upper case 3 and the main body case 3.
are formed respectively.

Further, a handset 8 and a holder 9 are installed on the left side of the main body case 2.

As shown in FIGS. 2 and 3, the holder 9 is provided with a hook button 13 having an operation button portion 12 elastically protruding from a through hole 11 provided in the upper wall surface 10 of the holder.

This hook button 11 is provided with a fulcrum shaft 15 at its base end via a support arm 14, and this fulcrum shaft 15 is provided with a bearing hole in a pair of left and right bearing members 16 integrally extending from the lower surface of the holder 9. 17 so as to be rotatable.

The bearing hole 17 has an opening 17a cut downward from a part of its circumferential surface, and the width of the opening 17a is smaller than the diameter of the bearing hole 17.

The fulcrum shaft 15 has flat portions 15 at both ends which are thinned so that they can be inserted into the openings 17a.
a is formed, and the flat portion 15
The fulcrum shaft 15 can be mounted in the bearing hole 17 by inserting the end 17a through the opening 17a. It is necessary to design the diameters of both the fulcrum shaft 15 and the bearing hole 17 in advance so that the fulcrum shaft 15 can rotate smoothly and without rattling when mounted in the bearing hole 17.

Reference numeral 18 denotes a notch for regulating the downward hanging of the hook button 13, which extends downward integrally from the upper wall surface 10 of the holder, and penetrates through the center opening hole 19 of the hook button 13, and extends downward from the lower edge of the hook button 13. Is receiving.

Further, below the hook button 13, there are provided a switch 20, a wiring board 21, etc., which switch the communication line in conjunction with the raising and lowering of the hook button.

When assembling the above-mentioned hook button 13 into the holder 9, as shown in FIG.
5a, rotate it to a substantially horizontal position as shown by the solid line in the figure, and engage the notch 18.

<Effects of the invention> As detailed above, the present invention forms a flat part by cutting out a part of the peripheral surface on the fulcrum shaft of the hook button provided in the holder of the telephone, and a bearing hole for receiving the fulcrum shaft. A part of the peripheral surface of the bearing hole is cut out to form an opening, and the width of the opening is smaller than the diameter of the bearing hole, and the flat part of the fulcrum shaft is inserted through the opening. Since it is configured to be installed in the bearing hole, it is easy to use with a single touch operation by simply inserting the flat part of the fulcrum shaft into the bearing hole from the opening, without using conventional fixing devices such as screws or caulking. The hook button can be attached to the holder, which reduces the number of parts and simplifies processing time, and since the structure is extremely simple, it has remarkable effects such as reducing total cost.
